Abstract

A measurement of the top quark pair-production cross section in the lepton+jets decay channel is presented. It is based on 4.6 fb-1 of s=7 TeV pp collision data collected during 2011 by the ATLAS experiment at the CERN Large Hadron Collider. A three-class, multidimensional event classifier based on support vector machines is used to differentiate tt¯ events from backgrounds. The tt¯ production cross section is found to be σtt¯=168.5±0.7(stat) -5.9+6.2(syst) -3.2+3.4(lumi) pb. The result is consistent with the Standard Model prediction based on QCD calculations at next-to-next-to-leading order.
